The information on this page refers to ACE Group.  ACE Limited acquired the Chubb Corporation on January 14, 2016, creating a global insurance leader operating under the renowned Chubb name.

ACE was established in 1985 by 34 founding sponsors to provide hard-to-find excess liability and directors and officers coverage.

Since then, ACE has evolved from a monoline excess insurer owned by its policyholders to a global publicly traded insurance company and one of the world's leading providers of commercial property and casualty insurance.
